Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, it relates to a silver halide color photographic material with improved image sharpness. It also suppresses fogging, has excellent storage stability, saves silver, and has light resistance (
The present invention relates to a silver halide photographic light-sensitive material for color photographic paper capable of obtaining color images with good fastness to light).

Generally, silver halide color photographic light-sensitive materials have three types of photographic silver halide emulsion layers selectively sensitized to have sensitivity to blue light, green light, and red light, coated on a support. For example, in silver halide photographic light-sensitive materials for color negatives, a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer are generally coated in this order from the exposed side. A bleachable yellow layer is provided between the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer to absorb the blue light that passes through the blue-sensitive silver halide emulsion layer. A single layer of filter is provided. Further, each emulsion layer is provided with other intermediate layers for various special purposes, and a protective layer as the outermost layer. Furthermore, for example, in a silver halide photographic light-sensitive material for color photographic paper, a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a blue-sensitive silver halide emulsion layer are generally arranged in this order from the exposed side. It is painted with
As in color negative/silver halide photographic light-sensitive materials, intermediate layers such as an ultraviolet absorbing layer, protective layers, etc. are provided for each specific purpose. It is also known that each of these silver halide emulsion layers is provided in a different arrangement from the above, and furthermore, each silver halide emulsion layer is sensitive to substantially the same wavelength range for each color light. have'2
It is also known to use photosensitive silver halide emulsion layers consisting of layers. In these silver halide color photographic materials, exposed silver halide grains are developed using an aromatic primary amine color developing agent as a color developing agent, and the resulting color developing agent is oxidized. A dye image is formed by reaction of the product with the dye-forming coupler. In this method, 1 usually phenolic or naphthol cyan couplers, 5-pyrazolones, pyrazolinobenzimidazoles, pyrazolotriazoles, indacylones or cyanocoupler are used to form cyan, magenta and yellow dye images, respectively. An acetyl magenta coupler and an acylacetamide yellow coupler are used. These dye-forming couplers are contained in the light-sensitive silver halide emulsion layer or in the developing solution.The present invention is applicable to color prints in which these couplers are non-diffusive and previously contained in the silver halide emulsion layer. This invention relates to silver halide photographic materials for paper.

[Prior Art] In recent years, high image quality silver halide color photographic light-sensitive materials have been desired in this industry. In the so-called color negative/positive system in which the final image is obtained by printing on a silver halide photographic light-sensitive material, the image quality of the silver halide photographic light-sensitive material is particularly important. The problem is that the image sharpness is low.

The reason why the image sharpness of silver halide photographic materials for color photographic paper is low is considered to be as follows.

In other words, since a white reflective support is used, light is scattered in the reflective support during exposure or reflected on the surface of the reflective support, resulting in very large irrations. This is the biggest cause.

[Problems to be Solved by the Invention] As a technique for preventing deterioration of image sharpness due to such halation and irradiation, it is known to provide a colored layer such as a /X ration prevention layer or a filter layer. A technique is known in which a coloring agent such as colloidal silver is added to an alkali-soluble resin or a hydrophilic colloid in such a colored layer. It goes without saying that it must be completely decolored in the processing steps after exposure of the photosensitive material, such as the development step, but it is also required to have excellent spectral absorption and be photochemically inert. . However, in the case of colloidal silver, it is not always possible to obtain sufficiently favorable spectral characteristics, which has a negative effect on color reproducibility, and also because it is not completely inert from a photographic chemical perspective, it causes undesirable fog in the silver halide emulsion layer. There were some shortcomings.

It is known that water-soluble dyes such as those described in No. 70,352 are incorporated into silver halide color photographic materials, but such dyes are not sufficient to prevent irradiation and halation. It was not possible to obtain high image sharpness.

Furthermore, regarding silver halide photographic light-sensitive materials for negatives, U.S. Pat.
．． Compounds that generate dyes and release development inhibitors by coupling with oxidized products of color developing crude drugs, such as those described in U.S. Patent No. 554, or U.S. Pat.
There is also a known technique for improving image sharpness using a compound (DIR compound) that releases a development inhibitor but does not form a dye by coupling with an oxidized form of a color developing agent, as described in the above issue. In the structure of a conventional silver halide photographic light-sensitive material for color photographic paper, even when an IR compound is used, almost no effect of improving image sharpness can be obtained.

Furthermore, there is also known a technique for improving image sharpness by processing the surface of a support to make it rough, such as in JP-A No. 48-89731, but the effect of improving image sharpness by this technique is limited. Very little.

On the other hand, due to the recent depletion of silver resources, the soaring price of silver is directly linked to the manufacturing cost of photographic materials, and has a large impact on the price. Therefore, there is an extremely strong demand for photographic materials that can save silver and be economically available at low cost.

Furthermore, there is also a strong demand for a silver halide color photographic material that can provide stable photographic properties even when stored raw for a long period of time.

Therefore, the inventor of the tree first proposed the technique shown in the specification of Japanese Patent Application No. 59-202060. This previously proposed technique is a silver halide color film having photographic constituent layers including at least a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer on a reflective support. In the photographic light-sensitive material, at least one of the photographic constituent layers contains at least one compound that releases a development-inhibiting substance or its precursor by reacting with an oxidized form of a color developing agent, and the green-sensitive material The present invention is a silver halide color photographic light-sensitive material characterized by containing at least one compound represented by the following general formula (III) in a silver halide emulsion layer.

General formula (III) (wherein, R5 is a halogen atom or a monovalent organic group that can be separated by a coupling reaction with an oxidized developing agent, R
s and R7 may be the same or different and each represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, an acylamino group, an alkylamino group, anilino group, an alkoxycarbonyl group, or an alkylthio group, and R6 and R7 are According to the previously proposed technology, it certainly has high image sharpness, suppresses fogging, and has excellent storage stability.
Moreover, it is possible to provide a silver halide color photographic material that can save silver.

As a result of further research into the previously proposed technology, the inventors discovered the following.

In the past, most of the magenta image-forming couplers that have been put into practical use and have been studied are mostly 5-pyrazolones. Dyes formed from 5-pyrazolone couplers have excellent fastness to heat and light, but 430
There is an unnecessary absorption with a yellow component near the n point,
This causes color turbidity.

A pyrazolobenzimidazole core is described in British Patent No. 1,047,812 as a magenta imaging coupler core that reduces this yellow component, and U.S. Pat.
, 770,447, and the pyrazolotriazole bone core described in Patent No. 3.725.0137 are known.

Among these, the dye formed from the IH-pyrazolo[3,2-C1-s-) lyazole coupler represented by the general formula ([lI] according to the previously proposed technology is used in a solvent such as ethyl acetate or dibutyl phthalate. , has little unnecessary absorption near 43Qnm, and has excellent sharp cut properties on the long wavelength side, but the formed azomethine dye has extremely low fastness to light, making it difficult to use in color photographic materials, especially print-type color photographs. This significantly impairs the performance of photosensitive materials.

The present invention has been made in view of the above, and has high image sharpness, suppresses fogging, and has excellent shelf life.
A technical object of the present invention is to provide a silver halide color photographic material that can save silver and provide color images with good light resistance.

The development inhibitor released from the DIR compound of the present invention in response to the density of an image during development inhibits development in a layer corresponding to one image density when the layer is a light-sensitive emulsion layer, On the other hand, it causes so-called intra-image effects such as improved image sharpness.

When the released development inhibitor diffuses into other layers, there are two types of so-called inter-image effects, such as a masking effect that suppresses the development of other layers in accordance with the density of the image in the diffusion source layer. It is possible to obtain image effects.

The DIR compound of the present invention can be added to a light-sensitive I\silver halide emulsion layer and/or a non-light-sensitive photographic constituent layer.
